Title: Las Pr
1 Is proud to present
- Lean Manufacturing for Direct Application
A very simple way to improve our operations
based on the logic concepts of the Toyota
Production System
2 - Lean Manufacturing for Direct Application
This presentation lasts approximately 20 minutes.
We recommend that you have paper pencil
handyto take notes of the subjects that you may
find ofinterest, so you can discuss them further
with some other members of your organization. We
will clarify anydoubts directly, through email,
telephone or personally.
3 - Lean Manufacturing for Direct Application
You will discover and identify through this
presentationa good number of opportunities
thatalready exist in your plant, to apply these
logicand simple practices and start
immediatelyto benefit from their implementation.
4 This is an individually readable presentation, it
is not intended to be used in the form of a
conference room presentation or a course. Our
materials for in site training are very
different, since the slides for those
presentations are guidelines for our instructors
and their audience.
5What is Lean Manufacturing?
- The purpose of this presentation is to show you
some characteristics of these practices that
contributed to the Japanese Miracle - Lean Manufacturing was born and raised in Japan.
It is based on U.S. statistician William Edwards
Demings principles and it was originally named
the Toyota Production System - The American Auto-Industry had to adopt this
system in order to survive and remain
competitive, therefore the need to switch the
name to Lean Manufacturing - Today, 100 of those plants operate under some
form of this system. It is the only smart
alternative to remain in the market
6Why Should We Adopt It?
- Manufacturing experts consider that in the years
to come it will not be possible to subsist for
any company that does not implement these
disciplines in their operations - The Global Economy has caused a stronger
competition in all kinds of businesses - Manufacturing industries face continuous
reduction in profit margins in order to keep a
share of the market - Each little savings will contribute to improve
the economy of the enterprise and its community - This is the time to perform the best use of each
and every one of the resources available - The Human Resource is perhaps the most critical
of all
7Which practices are these?
- TPM, Total Productive Maintenance
- The 5S philosophy, to improve cleanliness,
organization and utilization of the work areas.
This improves the use of time as well. - JIT Just in Time and the Pull System
- SMED (Single Minute Exchange of Dies) Quick
Setup - Zero Quality Control - Quality at the source - No
inspection - Production in Work Cells - One piece Flow - Cross
Training - Aditionally and complementarily Kanban Poke
Yoke are important elements we will define
them...
8How can we get to know them?
- This presentation allows for us to share the
general characteristics of these Lean
Manufacturing practices and their particular
applications. This way we can define if they are
a response to some of your needs. - We will overview each of them and will be able to
decide if one or the other is suitable for your
operation. - In some cases the application can be appropriate
just in a small part of your plant, but it will
for sure be very cost effective. - The training modules, either in electronic form
(like this presentation) or through our on site
hands-on coaching directly in your plant, cover
thoroughly and in detail the implementation
process. We provide a continued online or
telephone support for one full year at no extra
cost.
9TPM Total Productive Maintenance
- TPM is without a doubt an excellent starting
point in this series of positive changes. It
conciliates two traditionally antagonistic areas
of the productive environment. - The maintenance tasks are developed through a
cooperative activity with production operators.
They receive a valuable training which builds
more self confidence and empowers them to make
decisions about their equipment. As a result, the
equipment becomes more reliable and the
Operation, and Life Cycle Costs are reduced. It
is a Win-Win situation for the whole
organization. - The level of satisfaction and morale among the
personnel raises and a feeling of ownership
develops towards the equipment, the product and
the company.
10TPM Total Productive Maintenance
- The elements of technical knowledge acquired by
the operator represent a source of pride for him
and also more job security. - As a whole, the implementation has three
objectives interesting to all of us That is to
make the operation... - easier
- safer
- more productive
- TPM has three main goals
- Zero Breakdowns
- Zero Defects
- Zero Accidents
- The key to these accomplishments is the
development of a true new way of doing things. A
new management style.
11How to Achieve Implementation?
- All the changes required to adopt the new
disciplines are possible through a gradual
continual implementation. - Whatever our plan or schedule, we have to start
with ONE machine or Work Station. - We will select it with this criteria
- It must be an important operation within the
process - It must be visible to everyone in the
organization - We must know the actual conditions and
performance before the implementation effort - We must broadcast the support that TPM is getting
from top management and create awareness that it
is a permanent change in the process and the
attitude. - Show each one in the organization how they will
benefit from TPM. This will help get their
support.
12What Are The Benefits?
- 1.- To secure that the company will remain in the
market, therefore the job source. - 2.- A higher level of education and training
makes everyone more valuable inside and outside
of the working environment. - 3.- Lean Manufacturing is The Present and The
Future of the World Class Industry - 4.- Higher productivity always translates into
benefits for all the organization and the
community.
Each person will have to realize how this change
will benefit them. It is not about convincing
people.- One of the big errors we frequently
incur, is to ask people to work for our
objectives, instead of letting them see how their
own needs and aspirations can be satisfied and
achieved through their participation. That is the
motivation that each person can create on their
own.
13What are the 5S s?
- It is a set of 5 Japanese words
- Seiri - Sort
- Seiton - Set in place
- Seiso - Shine
- Seiketso - Standardize
- Sitsuke - Sustain
- In essence it is about
- Eliminate from the work area anything that
doesnt belong in it - Assign one logic place for each tool or material
that belongs in the area and have it always in
its place - Clean the area as never before
- Establish new conditions as the standard
- Sustain the effort so you do not lose what you
have achieved
14Just in Time...?
- Indeed, we used to think that in order to assure
production, we were supposed to have large
volumes of raw materials. That concept did have
several disadvantages though - Too much investment in inventories
- Risk of damaging materials
- Possible changes in design would have to wait
- Large spaces dedicated to storage
- Longer distances to do anything in the plant
- What did Toyota do?
- They established punctual delivery deals with
each supplier in exchange for continual loyalty - They reduced inventories in more than 70
- The areas and distances were shortened up to 50
15Just in Time...?
- Today each supplier knows exactly how many parts
he has to deliver in which spot of the plant and
at what time, (in some cases more than one
delivery per day and even one each hour). Storage
and receiving areas have been minimized. - As well as the amount of materials in stock, the
areas were also substantially reduced, and so
were the distances that each operation requires
for the operator to cover. Material handling was
minimized. - We will talk ahead about Kanban, a simplified
system to ease operations related to production
control, supplies, work in process and material
handling in general. - Along with JIT, we will analyze the pull
systems. This is about the volume and speed being
controlled basically by the following step in the
process. The final production line is regulated
by the final consumer.
16Pull system...
- The simplest way to illustrate and understand
this system is to think of the modern
supermarket. In this kind of business, the
storage areas have practically vanished... - We can see a good number of people who do not
work there, replenishing the shelves with their
products. They are the suppliers of products and
work for manufacturers or distributors of those
products. They are performing a Just In Time
delivery, but the volume of products that they
deliver is not read from a purchasing order of
the supermarket. They can only deliver the amount
of product that final consumers pulled from the
shelves. Therefore the name of the system. - The same process takes place in many factories
where some suppliers through an agreement keep a
pre-defined stock of Screws, nuts, bolts, hoses,
cables so that the consumers (in this case
operators or maintenance technicians), pull
from those strategically located supply centers.
This simplifies operations.
17Kanban, a Tool for Simplification
- Closely associated with JIT and the Pull System
efficiency, Kanban is a concept based on visual
items like tags, cards, banners, boxes, trays,
etc. - This is about creativity. We can use cards or
tagged or color coded boxes, trays, etc. to
identify one product or material being handled in
the system. Those cards or tags, boxes, bins,
trays, etc. will be used in a way that we will
determine conventionally. - Without a complex computerized system, these
elements will be generating visual, clear
information that we will be able to use in the
control of materials or the process itself. - Example at an automobile manufacturing facility
- A simple color coded card with a few signs,
letters or numbers tells everybodywhat
accessories or features have to be installed on
a vehicle on the assembly line...
18SMED?
- Single Minute Exchange of Dies is the name
given to a discipline focused on simplifying
machine setups. This allowed for stamping
machines to go from 4 or more hours to few
minutes in their set up or die exchange
processes. - Using locating or self centering pins instead of
bolts, fast setting clamps, sliding rails, wheel
mounted parts, special cranes, divided covers,
etc. set-up times are cut to just a few minutes. - These techniques are comparable to the process of
removing and replacing a set of tires in a racing
car with just one bolt each and in just 5 or 6
seconds. Right! We are in a competition,
remember? - We must be very careful though, so we do not
compromise safety or security of the operation
in search for speed.
19Example?
- In many cases, we can produce a special tool with
minimal cost and excellent results. - A special tool can be, for example, a simple T
handle made of steel tube with an hex or allen
point or a socket wrench attached. This will ease
some difficult to reach spots in a machine or
will eliminate the need for other tools to be
brought each time to the operation. It will also
make it safer.
20Clamps for Quick Release
- There are a number of clamps and other hardware
that will help accomplish the projectsto
simplify your operations. - Some of them may be manually operatedwhile
others may be pneumatic or even hydraulic. - These clamps are just an example of the many
resources that we can use to make our setups
easier, safer and faster.
21Guided Bolts?
In the case of a bolt that has to be used over
and over again to affix a tool, an extended shaft
guide will help to get it done easier and faster,
since it will not allow for the thread to be
misaligned.When possible,make it aWingnut!
22Zero Quality Control
- Quality is always a very complex concept and it
applies not only to our final product, but to
each condition, operation and action. - Traditionally, inspection was the way to prevent
a defective piece from leaving the plant. - Today jidoka is the real concept of quality.
Jidoka means Autonomous Control and that is
what Quality at the source is about. - We achieve Jidoka when we create ideas that will
help to stop the production when a tool or
material is out of specs, when the pressure is
not enough to stamp a part with total quality. I
just remembered those old tubular knitting
machines that would stop as soon as one of the
treads was broken. Quality control applied before
we have a bad product. - Poka Yoke is Japanese for Mistake-Proofing
- Prevention stops loses before they occur.
23Zero Quality Control
- As in most of these disciplines, training will be
the key. Operators and everyone in the
organization must learn the signs of bad quality. - Specifications have to be clear and well known by
each person, whatever the position. - In many cases people who are in constant touch
with the materials and sub assemblies know how to
detect errors and defects and will be able to
help create poka yoke (error-proof) measures. - Some operators will be trained to perform
adjustments and minor repairs that in the past
wouldve required maintenance technicians and
caused down time. - This level of training will raise the commitment
and ownership over the operation.
24What is a Work Cell?
- One of the most important changes implemented by
the Toyota Production System was the Work Cell
concept. - As in all these disciplines, the Work Cells
success comes from the combination and exchange
of skills among a small group of people who form
a trustworthy and highly respected Team... - They own the cell and make one product or
sub-assembly at the time. This is the base for
one piece flow - Autonomous quality, that is their product does
not have to be inspected, they know it is within
specs - Multi-disciplinary. All the people can run all
the tasks - They are friends among them and are always
willing to help and support each other - They know their product, equipment,materials and
tools
25What is the Key Element?
- CHANGE is the Key Element in all these
accomplishments... - Training becomes a part of the everyday routine
- The old idea of a few knowledgeable people
hoarding secrets is replaced by the will to learn
and to share all that we know - The power is now based on the mutual respect and
not in the hierarchical assignments - Leadership substitutes for authority and
positions represent our levels of responsibility
towards the people in all the other jobs - No doubt, this is a series of cultural changes to
be assimilated - This is the task that we can help develop.
- Thank you for watching this presentation. We
look forward to being of service to your firm.
